I just got some 168 grain ttsx's I plan on using in my. 300wsm with H4831sc. It may not be the ideal powder, but I have four pound sof it...

Any pet loads out there? I'll be happy with running them around 2900fps or so out of my Ruger's 22" pipe.

Hummm, ok but I understood that Barnes data for similar weight TSX's would apply to TTSX's.

I already have some load data gleaned from the internet (Barnes site and others), but am looking for someone actually using that bullet for an idea of what to expect.

TSX/MRX/TTSX data is all the same, and suspiciously close to most other jacketed bullets. Pressure can get a bit higher a bit faster as the TSX/TTSX are longer than a jacketed bullet since lead is obviously denser than copper.
 
"...Barnes data for similar weight..." Yep. You still load for the bullet weight, just not using, say, Hodgdon 168 grain H4831 data. Barnes does say on their site to contact them for data not on their site. They really want you to buy their manual though. $25.98US through their site.
 
rommelrommel, I believe that TSX/TTSX produce less pressure than regular jacketed bullets. This is allegedly due to the three grooves in the jacket which result in a smaller bearing surface.

Because of the grooves,(which can be more than three),the tsx/ttsx produce less pressure than a standard x bullet,but not normally less pressure than a cup and core bullet.

The X bullet had a reputation for producing a lot of pressure due to no grooves and the deeper seating depth, the TSX et al solved one of the issues with grooves, but not the fact that the bullets are long.

I look at the barnes data and normal jacketed data, and just work up from there. There isn't a lot of difference usually, the barnes data is usually in the spread if you have a few different manuals.
 
H4350 is the best powder for the bullet in the 300 WSM. I can't remember the load, but I was running just over 3100 fps. The load was worked up when Barnes still believed you could exceed max loads from the Barnes #3 for TSX bullets and the load was I think 1 gr over the listed max for the old plain X bullet.
